` E. W. GALE,

OF MONROETON, PENNSYLVANIA, ASSIGNOR TO HIM- IMPROVED HORSE CANT-300K.

The Schedule referred to n these Letters Patent and making part o! the same.

To all whom it may concern:

Be it known that I, E. W. GALE, of Monroeton, in the county of Bradford, and State of Pennsylvania, have invented a new andimproved Horse Gant-Hook; and I do hereby declare that the following is a full,

clear,fand exact description of the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, making a part of this specication. E

This invention relates to a new and improved canthook, which is designed to be operated, or have the power applied to it by a horse or other draughtanimal.

The object of the invention is to obtain a device for raising, lifting, and adjusting articles by a very simple contrivance, which may be economically constructed,

i very readily applied ,and adjusted for work, and which will be far more efioient than the ordinary hand canthooks hitherto used.

To enable those skilled in the art to fully understand and construct my invention, I will proceed t0 describe it.

In the accompanying sheet of drawings- Figure 1 is a side view of -my invention.

Figure 2, an edge view of the same.

Similar letters of reference indicate corresponding parts in the two figures.

A represents the upright of my improved canthook. This upright may be of any suitable ordesired dimensions, but the size which'probably will be most generally used will be, length'from eight to `ten feet, and the lower portion about five inches wide at each side, a good hard wood beingl used as a material, Y such, for instance, as hickory, ash, or white oak. The

outer end of the upright is encompassed by an iron band or ferrule, a, and a hook, B, is driven in said end, to which hook the draught-animal is connected or attached.

C is the anchor or fulcrum, which may be of any suitable dimensions, say from twenty-eight to thirty inches,'and rounded from each end upward, forming quarter circles, as shown at b b. This anchor or fulycrum sinserted in a mortise made centrally iu the inner end of the upright, and secured in said mortiser by bolts c, which pass through the upright and anchor.

D D are vtwo hooks, the. shanks of which pass through-a metal plate, d, secured to one side of the upright, and also through the latter, and have screwnuts c on the outer ends of their shanks, to hold them firmly iu position. These hooks may be from nine tol twelve inches apart. f

E is a chain, of any suitable length, and having a hook, F, at its lower end. This chain may be fitted on either of thehooks, D or D.

The operation is asfollows:

The lower end of the chain E is secured to the article to be raised, and adjusted by means of the hook F, the anchor or fulcrum G resting upon the ground, and the upright A being in a vertical position, or nearly so.

The animal, in moving or starting along, draws the upright A over, as indicated by the A dotted lines in tlg. l, and the article to be raised, lifted, and adjusted, and which is connected by the hook F-to the chain E, is raised and moi-'ed by this drawing over of the upright, a result due to the anchor or fulcrum C.

When the chain E is suspended onthe lower hook D', the leverage-power is increased, but the speed of the movement of the article to be raised is correspondently decreased, and the height or elevation of said article c'rrespondently diminished.

This device maybe constructed at a very small cost, and applied to its work and operated through the medium of a draught-animal with the greatest facility.

Having thus described my invention,

What I claim as new, and desire to secure by Letters Patent, is-

The herein-described horse-power cant-hook, coni.

sisting of an upright, A, with hooks -D D' at different elevations, the chain E with book F, the hook B, and' Vfulcrum-block O, when the latter has astraigbt base,

and the chain E is made adjustable in its attachment to the'uprigbt, all as herein set forth, and for the purpose specified.

E. W.GALE.
